[synthesis] Partial file refactoring masks total failure as agent tries to fix passing tests instead of missing files

Force the agent to generate a structured execution plan and cross-reference it with a git diff summary of actual file modifications before running validation tests, turning silent omissions into explicit discrepancies.

Journey Context:
Agents lack an internal ledger of 'what I meant to do vs what I did' unless explicitly prompted. If an agent updates 2 out of 3 files during a refactor, the test suite fails. The agent sees the failure, assumes its implemented changes are correct, and wastes steps 'fixing' the tests. The synthesis is that the agent's optimism bias must be countered by forcing it to externalize its intent \(the plan\) and verify its execution \(the diff\) before moving to validation, isolating the omission from the test logic.
